Cambridge organoids turn 'irreversible' nerve damage into a question of switches

Miniature brain-and-spinal-cord systems grown in the lab suggest that what is often treated as irreversible nerve damage may still have a biological switch.

Guava shifts the anemia question to absorption, not just iron pills

Guava juice is not an anemia cure, but a new review suggests it could be a cheap nutritional amplifier for iron therapy where low blood levels remain a public-health burden.

Pulse oximeters and the FDA warning: one oxygen number can delay care for Black patients

The problem with pulse oximeters is not one number on a screen, but the way that number can decide who gets attention, follow-up testing and faster care.

A tiny uterine model points to a bigger mystery: tissue repair without scars

A uterine-lining organoid lets researchers watch tissue shed and repair without forming scars.

Regeneration has a genetic clue, but medicine still needs an off switch

Researchers linked a set of SP genes to regeneration in axolotls, zebrafish and mice, opening an early path to understanding tissue repair.

One brain scan could give doctors more than anatomy

University of Illinois researchers demonstrated an MRI framework that measures more than 20 brain biomarkers in one scan.

Immune-response AI looks strong in the lab. Patients are the harder test

A University of South Florida study shows PanPep performs well in the lab but much worse in realistic immune-response scenarios.

A bloodstream therapy could change how damaged hearts begin to heal

Automated evaluation can scale safety checks, but it must not pretend to be diagnosis.

AI can spot the diagnosis, but emergency medicine still needs a human in charge

A breast cancer study mapped 78 paired tumors and metastases, showing how metabolically reprogrammed cells suppress immune response in lymph nodes.

The robot can find a heart scan on a model. Patients are the real test

Concordia's robot can find a cardiac ultrasound window, but patients are still the next hurdle.

MIT’s chaotic laser could let scientists watch brain drugs reach their target

Sixian You's team published their counterintuitive finding in Nature Methods on April 28.

Pregnancy’s Hidden Cell Map Reveals New Risks—But No Cures Yet

Researchers at and collaborators mapped 350,000+ cells across early and late pregnancy stages to build the first of the maternal-fetal interface.

New cell map reveals pregnancy risks at single-cell level

UC San Francisco’s single-cell atlas of pregnancy reveals new cell types linked to preeclampsia, but remains purely research-stage.

Cervix-on-a-chip: A lab model that finally mimics real STI risks

Cambridge chemists turned a botched reaction into a method that uses LED light to edit drug molecules—no toxic solvents required.

The exposome atlas: a map of modest but real health signals

T cells—immune system’s off-meta pick—just outplayed antibodies in a *Cell Reports* study, targeting viral ‘core files’ instead of mutable cosmetics.

Autism risk genes cross ancestries—but limits remain

Rare mutations in *CHD8* and *SCN2A*—genes long tied to autism in European populations—now appear equally significant in Latin American cohorts, per a 10,000-person study.

China’s biotech surge collides with NIH’s tightened collaboration rules

CVS faces a settlement over manipulated insulin prices, potentially saving Americans $7 billion.

A 30-million-cell atlas of the human brain—with limits

The lymph node no longer looks like a simple stop on breast cancer’s route

A breast cancer study mapped 78 paired tumors and metastases, showing how metabolically reprogrammed cells suppress immune response in lymph nodes.

A Dravet therapy is testing a shift from seizure control to the gene

Zorevunersen reduced seizures by up to 91 percent in early trials involving children with Dravet syndrome.
